The present invention relates to novel fluorine containing compounds, methods for their preparation, the intermediates of the synthesis, their use as diagnostic agents, especially for imaging of thrombi. The invention relates to positron emission tomography (PET) agents and associated precursor reagents, and methods for producing such radiolabeled agents for imaging of thrombi in a mammalian body. More particulariy, the invention relates to small, nonpeptide, high-affinity, specific-binding glycoprotein llb/IIIa antagonists for imaging of thrombi.
